NEW YORK ( TheStreet) -- "This is a stubborn market," Jim Cramer told the viewers of his "Mad Money" TV show Friday. That's why he said investors need a good game plan for next week's trading.

On Tuesday, electronics retailer BestBuy ( BBY) reports its earnings. Cramer said this company needs to beat 45 cents a share to impress Wall Street, but since the stock hasn't run up ahead of the earnings, he'd be a buyer on Monday.

Cramer said he's also bullish on software maker Adobe ( ADBE). With 10 analysts rating the stock a "hold" or worse, Cramer said this stock is another one worth getting in on ahead of their earnings.

On Wednesday, Boeing's ( BA) 787 Dreamliner is scheduled to fly. Cramer said he's bullish on Boeing and on its suppliers like Honeywell ( HON), a stock which he owns for his charitable trust, Action Alerts PLUS , and Precision Castparts ( PCP).

Cramer was also bullish on Joy Global ( JOYG), a stock that's up 105% since he first recommended it on Dec 17, 2008. He also recommended General Mills ( GIS), ahead of its earnings, and Darden Restaurants ( DRI) on the strength of the American consumer.

Cramer told viewers they need to be watching companies like Paychex ( PAYX) and Discover Financial ( DFS) to further gauge the health of the economy and job market.

Finally, Cramer said he'll be watching both Research In Motion ( RIMM) and Palm ( PALM). Cramer said one of these two will likely say something to bring the group down, and he'd use the weakness to buy more Apple ( AAPL).

Wireless Infrastructure Play

For "Speculation Friday," Cramer returned to a thesis he touted earlier this year, the growth in wireless infrastructure. He said the thesis remains strong, there is still not enough wireless capacity in the U.S. to handle the growing demands of smart phones.

On Sept. 10, Cramer recommended American Tower ( AMT) and Crown Castle ( CCI), two of the largest cellular tower players in the country. Since then, the stocks are up 15% and 24% respectively.

Cramer also recommended the smaller tower stocks, including SBA Communications ( SBAC), which is up 29% since September. Cramer said this company, which operates only 7,800 cell towers compared to the big players with 20,000 towers, has a lot of room to run and is buying back its own stock to boot.

On Sept 11, Cramer expanded on his thesis and recommended backhaul providers Ceragon Networks ( CRNT) and Harris Stratex ( HSTX), two companies which help connect cellular traffic to the Internet.

Ceragon is up 48% since the recommendation, with Harris Stratex up only fractionally. Cramer said he'd take some profits in Ceragon, but he remains a big fan of the company which is growing earnings at 17.5%. Cramer said Harris Stratex is still worth owning, but he's not as enthusiastic.

On Oct. 14, yet another cell tower company came public, this one called DragonWare ( DRWI). Cramer said unlike the others he's mentioned, DragonWare is far too speculative to invest in given that 77% of the company's revenues come from a single company, Clearwire ( CLWR).

Challenging Times

Closing out his "Invest In America" series, Cramer once again welcomed Dan DiMicco, president and CEO of steelmaker Nucor ( NUE), to the show to discuss the steel industry and the challenges facing the America economy.

DiMicco once again sounded the alarm, saying that the problems facing the country are bigger than people realize, but noted that some in Congress are beginning to wake up to the issues at hand. DiMicco said it's critical for the country to get its budget and trade deficits under control. He said the country needs to focus on recovery and job growth, not the president's current list of priorities.

DiMicco also stressed the need for energy independence and better infrastructure. He said America needs $2.2 trillion dollars work of infrastructure spending to get the country back on track creating jobs and economic growth. He said both of these initiatives will require the president to "jump in with both feet."

Turning to the steel industry, DiMicco remained cautious on the industry's outlook. He said that rising input costs are boosting the price of steel. But, he noted, the increased demand is not sustainable. DiMicco said he won't know if the demand is real until the first quarter of 2010.

Mad Mail

Cramer told a viewer that Fluor ( FLR) is a buy given its huge backlog of business.

Cramer told a second viewer that Brazilian paper maker Fibria Celulose ( FBR) is a buy.

Citigroup boosted CEO Michael Corbat's pay to $23 million, even as the bank failed to meet the CEO's own profitability goal for a third straight year, and as it reported a full-year net loss of $6.2 billion due to the write-off of tax credits that management had touted as a competitive advantage.

Last week's market drop rattled investors with concerns about rising inflation and interest rates. Yet with the economy progressing at a slower pace than in past cycles, there's plenty of time left to profit from bank stocks like JPMorgan, Bank of America and Citigroup, typically among the biggest beneficiaries of economic growth, argues Sandler O'Neill.
